- Drought12/01/2023
Vernon
$26.9M damage
What happened
Enough rain fell towards the middle to end of the month to improve conditions back to moderate drought. Farm and stock ponds continued to see impacts along with ground water levels and reservoirs. Crop loss estimates notated in this month encompass losses from continued drought since spring 2023.
- Hail2.5" hail04/26/2026
Bronaugh, Vernon County
$25M damage
What happened
A severe thunderstorm produced hail from golf ball to tennis balls in size over a swath nearly 32 miles in length from south of Nevada, MO to locations north and east of Nevada. Along this mostly rural path, damage occurred to some roofs of homes and structures, vehicles, multiple RV's, equipment and crops.
- Drought08/01/2012
Vernon
$18.69M damage
What happened
The U.S Drought Monitor continued to report Extreme Drought (D3) to Exceptional Drought (D4) throughout the month of August. The region started seeing some rainfall by the end of the month. The COOP station near Horton reported 2.87 of rainfall for the month of August. This is a continuation of the drought that began across the region in June. As a result of the limited rainfall combined with the excessive heat, the USDA Service center in Vernon County indicated that crop losses were 75 percent of the spring planting. Many farmers and ranchers reported having to feed hay as pastures stopped growing and became dry through the month which added to operation costs. Monetary crop loss figures are estimates using information from the National Agricultural Statistics database, local FSA and USDA offices and other local, state or federal agency information. Livestock losses, if they occurred or were reported are listed in the property section.
- Drought02/01/2023
Vernon
$12.3M damage
What happened
Rainfall through the month allowed for improvement across the county though Moderate (D1) Drought conditions continued across the region through the end of February. The US Drought Monitor indicated only the southwestern third of the county remained in Moderate (D1) Drought with the rest of the county having improved to either Abnormally (D0) dry or no drought. Impacts across the region were primarily felt in larger scale agriculture with farm and stock ponds low but improved. Dry conditions caused grasses to dry and significantly impact hay production causing losses in hay cutting. Many farmers saw impacts to row crops such as soy beans, corn and other specialty crops. Crop loss estimates notated in this month encompass losses from initial drought development in 2022.
- Frost/Freeze04/08/2007
Vernon
$11.76M damage
What happened
Unusually warm conditions during the month of March caused early season growth in vegetation across the Missouri Ozarks. Hay along with the wheat crop had began to mature. During the nights of April 7th through the 9th, temperatures dropped into the upper teens to mid 20s, causing a hard freeze on matured vegetation. The wheat crop suffered approximately 90% damage. Hay crops along with fescue seed also sustained major damage. Total crop losses for 34 counties across the southwestern quadrant of Missouri were estimated at $147,905,541.
